To all 'whom t may concern.

Be it known that I, LUTHER P. CnEAsY, a citizen of the United States,residing at Catawissa, in the county ofColumbla and State ofPennsylvania,haveg'nvented new and useful Improvements i'n ops, of wh1chthe following 1s a specification.

This invention relates to improvements in mops and has for an object theprovlsion of a mop which may be either motor or hand operated andoperated over a ioor or other surface to quicklyT and eifectually cleanthe latter.

Another object of the invention is the provision of a mop of the abovecharacter in which the mop per se will be thoroughly cleaned during themopping operation to effectually remove dirty water before the mop againcomes in contact with the iioor.

Another object of the invention is the provision of a mop of the abovecharacter which is simple in construction and operatlon land in whichthe mop per se may be readily removed and replaced.

With the above and other objects in view,

the invention further includes the following novel features and detailsof construction, to be hereinafter more fully described, illustrated inthe accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is an elevation of a mop constructed inaccordance with the invention.

Figure 2 is a section on the line 2--2 o f Figure 1.

Figure 3 is an enlarged fragmentary view illustrating the means foradjusting the auxiliary frame.

Figure 4 is an enlarged section on the line 4-4 of Figure 2. Y

Figure 5 is a similar view on the line 5-5 of Figure 2.

Figure 6 is a detail perspective view of the agitator roll. y

Figure 7 is an elevation showing a hand operated mop.

Figure 8 isl an enlarged fragmentary view of a portion of the mop belt.

Figure 9 is a similar view of a different form of belt.

Figure 10 is a section on the line 10-10 of F1 re 9.

Re erring to the drawings in detail where in like characters ofreference denote corresponding parts, the invention is shown asVcomprisingv a main frame which includes `substantla l triangular sidemembers 15 which are connected by shafts 16, the latter supportlngflanged guide rollers 17. -Passlng over the rollers `17 is a belt 18which forms the mop per se and which may be made of any suitablematerial. For exampleit may be made entirelyI of mop material, or 1t maybe made of strips of mop material indicated at 19 in Figure 8 of thedrawings and shown as arranged diagonally across a canvas or othersuitable belt 20.. Where it is desired to use the mop for cement orother relatively rough ioors, or where an excess amount of dirt is to beremoved, the lbelt may be in the form of a brush as indicated at'21 inFigures 9 and 10 of the drawings.

The belt 18 is yieldin ly forced into contact with the floor or ot ersurface by compressible rollers 22' which are mounted between the sidemembers 15 of the frame and which are supported upon shafts 23.

The frame is supported upon rollers 24 which are shown in detail inFigure 5 of the drawings. These rollers are adjustably secured to theframe and for this purpose are connected to substantially U-shapedbrackets 25, having slots 26 therein for the passage of screws 27. Thumb'nuts 28 are mounted upon the screws 27 and act to adjustably secure thebrackets 25' to the frame.

Supported within the frame upon brackets 29 is a tank 30 which isadapted to containwater or other suitable cleansing liquid. This tank issubstantially triangular and includes upwardly and inwardly inclinedwalls 31 whose fupper edges define a restricted top or mouth. The tank30 is provided with a drain opening which is normally closed by a plug32.

Located within the tank 30 is an auxiliary frame which includes spacedsubstantially triangular side members 33. These members are providedwith extensions 34 having slots 35 therein, while pins or studs 36extend from the side members 15 of the first mentioned frame into vtheslots 25 and act to guide the auxiliary frame.

The side members of the auxiliaryframe are connected by" shafts 37, thelowermost shaft having mounted thereon a flanged roller 38 around whichpasses the belt 18 so that the latter is guided downward through the jtank 30 and through the water within the tank. The opposite end of theauxiliary frame carries combined squeezing and guide rollers 39 and 40,the latter being spring pressed as indicated at 41 so as to press uponthe belt 18 which passes between these rollers and remove surplus waterfrom the belt. The roller 39 has its shaft 37 arranged within the innerend of angular slots 42 provided in the side members 33 of the`auXiliaryframe, so that this roller 39 may be removed for the convenient removaland replacement of the belt 18. The rollers 39 and40 are provided withflanges similar to the rollers 17 and 38 which act to guide the belt.

The extensions 34 of the side members of the auxiliary frame are engagedby adjusting vscrews 43 which are mounted in the side members of themain frame as illustrated in detail in Figure 3 of the drawings. By

. means of these screws 43 the auxiliary frame may be adjusted to-adjust the belt. To maintain proper tension upon the belt the roller38is mounted in floating bearings 44 which are movable in slots 45provided in the side members 4'3 of the auxiliary frame, the bearingsbeing yieldingly forced in. one direction by means of springs 46.

The belt may be either motor or hand operated. In Figures 1 and 2 thereis illustrated a motor 46 which is supported upon the main frame andwhich is geared to the shaft 16 of one of the belt guiding rollers 17 bya train of gears 47.

Pivotally secured to the side members 15 of the main frame is a bail 48to which is secured a handle 49 to provide means for moving the m'opover the surface to be cleaned. v

For the purpose of insuring the removal .of dirty or wastewater from thebelt, the latter is engaged by an agitator. This agitator is in the formof a corrugated roller 50 which is mounted within the tank 30 and whichcontacts with the belt. Mounted upon the shaft of this roller is agrooved pulley 51 around which passes a drive belt 52. This belt alsopasses around a grooved pulley 53 mounted upon the shaft of the motor36', whereby the agitator roll 50 will be rapidly rotated against thebelt 18 to agitate the latter in its passage through lthe tank. Byforming the tank 30 as shown in Figure 2, the water agitated by the roll5() will be prevented from splashing out through the open top of thetank.

As shown in Figure 7, one of Ythe rollers 17'has secured thereon agrooved pulley 54 which is driven by a belt 55. This belt passes arounda pulley 56 which is mounted `other changes in its form, proportions and'minor details of construction and the right is herein reserved to makesuch changes as properly fall within the scope of the appended claims. jHaving described the invention what is claimed is 1. A mop comprising aframe, wheels supporting the frame, a water tank mounted within the.frame and provided with a restrictedopen top, an endless belt, strips ofmop material disposed diagonally across the belt -to provide a mop,guide rollers mounted within the lframe for guiding the belthorizontally along the lower portionV of the frame, spaced rollers ofcompressible materialengaging the horizontal portion ofthe belt to forcethe latter into active position, means for guiding the belt within thetank and means for driving the belt.

2. A mop comprising a frame, wheels supporting the frame, a water tankmounted within the frame and provided with a restricted open top, anendless belt, guide rollers mounted within the frame for guiding thebelt horizontally along the lower portion of the frame to provide a mop,spaced yieldable means engaging 'the horizontal portion of the belt toforce the latter into active position, a substantially triangular framelocated within the tank and having slots at one corner thereof, pinsextending from the first mentioned frame for entrance into the slots,rollers carried by the triangular frame for guiding the belt through thetank, adjusting screws carried by the iirst mentioned :trame andengaging the triangular frame to adjust the latter and means for drivingthe belt.
